Replace your old hanger with the XLC derailleur hanger DO-A13. Designed as a consumable component to preserve your frame in the event of a crash or damage to the drivetrain, the mech hanger is a crucial part of your bike. It keeps the gears running smoothly, keeping everything in line, so it’ll need replacing if it becomes damaged or worn. The XLC derailleur hanger DO-A13 is manufactured from aluminium, giving it anti-corrosion properties as well as being lightweight. It’s designed to be compatible with certain city, mountain, road, race and trekking bikes, but check that the shape is the same as your current bike’s derailleur hanger before purchasing. The hanger has two holes for you to attach to your frame and derailleur.
